For aarch64, the "info all-registers" output is very verbose. If you run this test using read1, it will timeout before the command output is done being read. Read line-by-line so we don't run into timeouts. gdb/testsuite/ChangeLog: 2021-04-27 Luis Machado <luis.machado@linaro.org> * gdb.xml/tdesc-reload.exp: Pass -lbl.
